3 GOALS This safety session teaches employees to: Understand how to choose, inspect, and use portable ladders correctly. Applicable Regulations: 29 CFR Proper ladder selection, inspection, and use can prevent falls and injuries. The Occupational Safety and Health Association (OSHA) standards cover ladder design as well as requirements for: Inspecting ladders and removing unsafe ladders from use; and Safe ways to climb and work on ladders. 2. Select the right ladder for the job. Use a ladder, not a chair or box, to reach heights. The ladder should be: Tall enough to reach the height you need. Rated to handle the combined weight of you, your materials, and your equipment. are rated I-A (holds 300 pounds); I (250 pounds); II (225 pounds); III (200 pounds. Not usually used on the job). Safe for the conditions: Don t use metal ladders around electricity, because metal is a conductor. 3. Inspect every ladder before using it. Don t use a ladder that has any missing or broken parts. Tag it as defective and remove it from service. Don t try to fix a ladder yourself. A ladder should have: No missing parts; Firmly attached slip-resistant steps, rungs, or cleats free of grease or oil; Tight support braces, bolts, screws, and spreaders; Lubricated metal parts; Safety feet; Rope in good condition (not worn or frayed); No splinters or sharp edges; and No dents or bent parts in metal ladders. 4. Set up a ladder firmly and properly. Place it on level floor or ground, with feet parallel to the surface it rests against. Place the ladder on wide boards if the ground is soft or broken. Extend the ladder at least three feet above the top support. Don t rest it on a window or window sash or in front of an unlocked door. Anchor the top. Tie the bottom, or have someone hold it. Set up straight and extension ladders at the proper angle. The distance from the base of the ladder to the wall or other vertical surface should be one fourth of the ladder s working length.

4 5. Climb and work on ladders safely. Wear shoes with clean, nonskid, nonleather soles. Allow only one person at a time on a ladder. Climb up and down facing the ladder with hand, on rungs ore side rails, and maintain 3 points of contact. Carry tools on a belt or rope or hoist. Work with one hand on the ladder. Don t stand on the top two stepladder steps or top four ladder rungs. Move slowly and cautiously on a ladder. Don t move a ladder while you re on it. Center your body on the ladder so your belt buckle is between the side rails. 6. Carry and store ladders properly. Carry a ladder with another person when possible. If you must carry alone, balance the center on your shoulder. Keep the front end above your head and the back end near the ground. Store ladders in a dry, ventilated area kept at a moderate temperature. Store ladders standing up, if possible. If they must lie down, support both ends and the middle to prevent sagging or warping. Don t keep anything on a stored ladder, or the ladder will warp. TRAINER OUTLINE 1025 A-2 DISCUSSION POINTS: Ask participants which jobs they perform that would be dangerous with a metal ladder. Ask for specific suggestions of how they would carry the tools and materials they use while working on ladders. CONCLUSION: Attention to portable ladder safety prevents injuries. Take the time to choose, inspect, and use a ladder safely. TEST YOUR KNOWLEDGE: Have your employees take the quiz. By testing their knowledge, you can judge their understanding of how to prevent these accidents and whether you need to review this important topic again soon.

5 Step Up to Portable Ladder Safety CHOOSE a ladder tall and strong enough for the job. CHECK that ladders have all parts in good condition, including: Slip-resistant steps or rungs Braces, bolts, screws, and spreaders Rope Safety feet TAG AND TURN IN any damaged or defective ladder. HANDOUT 1025 B-1 POSITION the ladder for steadiness with: Ground surface level Feet parallel to the wall at a distance that is equal to one-fourth the ladder working length At least 3 feet above top support with top anchored, and bottom tied or held WORK cautiously on a ladder to prevent falls. Remember to: Allow one person only on a ladder, wearing shoes with clean, nonskid soles. Face the ladder and hold both rails while climbing. Carry tools on a belt or rope or hoist. Stay below the top two stepladder steps or four top ladder rungs. Work with body centered, one hand on rail, and tools in hanger or holder. WARNING: Don t use a metal ladder around electricity!!
